White Flats Gold Project


Lease Status: Available   

Exploration Target: A high-grade Carlin-type gold deposit


Property Highlights:

  • White Flats has a strong Carlin-type signature that has been drilled only to shallow depths.
  • Surface rock chips up to 3.4 g/t gold; shallow drilling (max 820 feet) has intersected up to 0.2 g/t gold over 100 feet.
  • Narrow, linear gravity anomalies coincident with surface alteration and geochemistry suggest a strongly altered zone at depth.
  • The target will be a high grade deposit at moderate depths, like those drilled at the nearby Rain Underground and North Bullion deposits, with grades greater than 7 g/t gold.

Property Location:

White Flats is located in western Elko County, NV about 10 miles south of Elko and 11 miles northeast of the Rain Mine.  The land is composed of a combination of BLM and private mineral rights; the apparent primary target is wholly located on Genesis claims however.

Target Analogs:

Three high grade Carlin-type deposits have been drilled in the nearby Rain-Bullion District of the southern leg of the Carlin Trend.  These include the Rain Underground, the Saddle Deposit, and the recent discovery by Gold Standard Ventures of the blind North Bullion Deposit (which includes a recent intercept of 8.5M of 11.16 g/t Au) .

Geologic Setting:

The White Flats project is along a northwest trending gravity high located over exposures of upper Paleozoic clastic and carbonate rocks.  Host rocks of the Rain-Bullion district should lie at moderated depths below these units. Alteration consists of jasperoid development and decalcification, especially along a series of north and northeast trending faults.  Surface rock chips and soils are strongly anomalous in gold and Carlin-type pathfinders of arsenic, antimony, and mercury.

A detailed gravity survey shows strong linear anomalies in the southwest part of the property, coincident with strong alteration and geochemistry.  This suggests a zone of strong alteration at depth that would be constitute a primary drill target. 

History and Results:

The White Flats property was explored by BHP, Nevada North Resources, and Noranda in the 1990s.  Work during this period included mapping, rock chip sampling, soil sampling, a and the drilling of 18 reverse circulation drill holes to a maximum depth of 820 feet; only four holes were drilled deeper than 500 feet. Cassini Resources held the property for two years, terminating 2016 due to lack of funds.  Cassini conducted mapping, soil sampling, and a gravity survey but carried no drilling.

Rock chip sampling returned several plus 0.5 gram gold samples and soils are strongly anomalous with numerous plus 100 ppb Au anomalies.  Drilling to date has not been deep, with a maximum depth of 820 feet.  Most Noranda holes showed modest gold anomalies with the strongest 120 feet of 214 ppb gold; no assay results are available for the 9 BHP drill holes.  The detailed gravity survey identified at least two strong north-south trending structural/alteration features in the southwest part of the property.  The fact that these anomalies are so prominent with such a relatively insensitive tool as gravity suggest that they represent strong zones of alteration, likely density depleting decalcification such as that which hosts the high grade at North Bullion.

Potential and Exploration Scenario:  

The White Flats project hosts the uppermost levels of a classic Carlin-type gold system.  In the nearby Rain-Bullion district, such signatures have lead to the discovery of high grade deposits at moderate depths, with grades of over 7 g/t gold (0.2 opt Au).  These features suggest that White Flats represents a strong target for deeper drilling. The work to date has only begun to expose the potential and further exploration is strongly justified. Prior drilling was not deep enough to really test the system nor did it target structural features that could contain high grades of gold. Prior to drilling, further mapping and geophysics should be conducted to help delineate the extent of the system, the orientation of key structures, and the target depths for drilling.
